BELL.

SPECIFICATION forming part of Letters Patent No. 455,626, dated July 7, 1891.

To @ZZ whom it may concern:

Be it known that I, CHARLES J. KINTNER, a citizen of the United States, residing at New York, county of New York, and State of New York, have made a new and useful Invention in Bells, of which the following is a specification. g l

My invention is-directed particularly to improvements in tap or call bells of a mechaniro cal nature and such as are designed to imi'- tate in their operation theaction of electrical trembler-bells.

My invention has for its objects, first, the production of a cheap, simple, and eflicient I5 mechanical trembler bell adapted for use wherever such bells are needed; second, the construction of such a bell of as few parts as possible, so put together that they may be readily taken apart for repairs, (Kto. These `zo objects are accomplished by my improved bell, hereinafter described, and particularly claimed in the claims which follow this speciiication.

Referring to the drawings, Figure l is a plaILView of the base and operative parts of the apparatus, the bell being shown in dotted lines. Fig. 2 is a sectionalY and side elevational vew of the entire apparatus.

B represents the bell secured to a base B 3o on the upper shouldered end of an upright standard S, which acts also as a bearing for a loose sleeve O, provided with a loose gearwheel G, ratchet N, and pawl P at one end and a pinion K at the other end, said pinion being adapted to mesh with a rack R, carried by a lever L, pivotally secured to the base B by a screw S. A spiral spring E is attached at its opposite ends to the lever L and the base B.

4o O is a second sleeve journaled to an upright standard in the base B and carrying at its upper end a pinion T, which meshes with the gear-wheel G on sleeve O. At the lower end of sleeve O is an escapement-wheel H,

the teeth of which are adapted to actuate a verge F, pivotally secured to the base B', carrying a bell-clapper C at the free end of an arm D.

T and T2 arev thumb-levers, the former located lat the free end of lever L and the lattereither integral with the base Band struck Application filed April l, 1891. Serial No. 387,258. (No model.)`

up therefrom in the making of said base or secured thereto by screws, as shown.

The operationVA of the apparatus is as follows: The operator grasps the parts T and T2 between his thumb and linger and forces the lever L in the direction of the arrow, thus placing the spring E under stress, at the same time causing the pinion K, sleeve O, and ratchet-wheel N to rotate rapidly, so that the ,6o pawl P, under stress of spring E, will, when the pressure of the thumb and .finger is removed, cause the gear-wheel Gr to transmit motion to the pinion T, and hence ultimately to the escapement-pallet F, thereby causing the clapper O to rapidly strike the bell B a number of times.

It Will be understood that this improved form of bell may be adapted for door-bells by the use of a cord or wire attached to the lever 7c L at its free end, the base B being secured to the wall, the door, or any preferred location.

If desired, the ratchet-wheel N and pawl P may be done away with and the gear-Wheel G rigidly xed to sleeve O, in which event the bell will ring when the lever L is moved in either direction.

Having thus described myinvention, whatI claim, and desire to secure by Letters Patent 8o of the United States, is-

l. A mechanical trembler-bell having a pivoted operating-lever provided with apropelling-rack, a fixed thumb-lever secured to the` base, and intermediate gear mechanism operatively connected to an escapement-pallet carrying a bell-clapper, substantially as described..

2. A mechanical trembler-bell having a finger and a thumb-lever, the former being piv- 91 otally secured to the base and connected through intermediate gearing to a vibratory bell-clapper and the latter rigidly. secured to its base, substantially as described.

3. In amechanical trembler-bell, the com- 95 bination of the following elements: a xed thumb-piece secured to the base, a pivoted operating-lever having a retractile spring and a propelling-rack, a pinion meshing with the rack, and a gear-wheel carried by the same 'roo sleeve which sustains the pinion, said gear'- wheel meshing with a second pinion carried byafixed standard and operatively connected which supports the bell, zipinion T, an es- 1o with au escapement which drives 2m escapecapement H, and an escapement-pallet F, ment-pallet carrying a bell-dapper. su pportin g a bell-dapper C, all operating sub- 4. In a mechanical trembler-bell, the comstamtialyas described.

5 bination of the following elements: a ixed thumb-piece T2, a pivoted actuating-lever L, provided with a rack R and retractile spring l Witnesses:

E, a pinion K, gear-Wheel G, ratchet N, 'and M. L. BUTLER, pawl P, carried by a, sleeve O on the standard I GEO. H. STAYNER, J1.
